I just wanted to let the community know that I completed my first autonomous robot project and used something for the body which I haven't seen used yet.  Strong-Ties are cheap (58 cents each (US)) and worked rather well for us.  My blog captures a complete parts list, links, lessons learned, source code and a few videos.  If interested, please visit http://techdiy.tv and let me know what you think.

Thanks!

Interesting little robot. It seems like you are developing an eye toward "what can I use for robotics" when it comes to looking at things; while the use of metal tie plates for robotics isn't new, it does take a certain amount of insight until you get that "aha!" moment, then you start looking at everything like that (hmm - can I use that watermelon for a robot part? /joking - or am I?).

Regarding your tip about lubricating drill bits with oil: Yes, this is paramount. In fact, there exist special purpose oils just for the task called "cutting lubricants". On a per ounce basis, though, they don't come cheap. The best oil to use, one recommended by tons of old-time machinists stretching back decades or more - is common bacon grease! It doesn't matter if it is rancid or not. Save it up, put it in a small jar and stick it in your fridge (maybe with a warning sticker). Dab it out as needed. Best part: As it warms up, you get the wonderful smell of bacon suffusing your shop - what could be better?

/note: If you're a vegetarian or vegan, then you might be SOL on the bacon grease...
I will not respond to Arduino help PM's from random forum users; if you have such a question, start a new topic thread.

Interesting video!
When the BOT passes the door, it seems confused and makes a ( IMHO unnessesary ) turn.

Instead of using POTs to syncronize motorspeeds, you better use encoders.

happy coding

It's not my fault when my Posts are full of Errors. This stupid autocorrection from my browser is set up for german grammar.

Just FYI...
TechDIY.tv has moved to http://michaelwittmer.com/
I will be rebuilding the autonomous bot again for my son so it will be covered on the new site.  We gave the 1st one to my dad/my son's grandfather as a present. For now, you can see the original here if interested: http://wp.me/p46r1I-3T
